Abstract: ABSTRACT OF THE DISCLOSURE:        3-Methyl piperidine is produced in high yields by hy-drogenating 2-methyl glutaric acid dinitrile in the presence of a nickel catalyst.  The use of a nickel catalyst, such as finely divided nickel or nickel on a support, promotes the for-mation of 3-methyl piperidine and suppresses formation of the 2-methyl -1,5-diaminopentane which would normally be expected. 3-Methyl piperidine is used as a vulcanisation accelerator and as an  additive for lubricating oils; it is also an interme-diate product for the production of nicotine acid.

Abstract: TRANSMISSION RATIO CONTROL SYSTEM     ABSTRACT OF THE DISCLOSURE   A transmission ratio control system including an engine having fuel supply means for controlling engine power, a hydrostatic transmission driven by the engine including means for varying transmission ratio, a ratio control valve for controlling the ration varying means, means for applying a bias to the ratio control valve proportional to engine speed, and means responsive to system pressure in the hydrostatic transmission for applying an opposing bias to the ratio control valve proportional to engine torque.  In operation, the fuel supply means calls for a predetermined amount of power to be delivered by the engine and the system pressure in the hydrostatic transmission is utilized and as modified by the transmission ratio to provide an indication of engine torque, with the ratio control valve being responsive to the engine speed and the engine torque to vary the transmission ratio to obtain a desired power/speed curve for operation of the engine.  The system also includes a brake valve alternatively operable to deliver a signal simulating an engine torque level to correspond to the desired engine speed.

Abstract: ABSTRACT The invention is concerned with digital communication systems and there is disclosed a digital telephone system wherein any digital telephone may be switched, by control from a local exchange, between a power-up state wherein continuous operating power is consumed by the telephone and a power-down state wherein the telephone is effectively turned off except for the consumption of a small amount of power sufficient only to enable communication between the telephone and the exchange.  A telephone is powered-up by detecting, at the telephone, a control signal in the digital data trans-mitted from the exchange to the telephone.  Each telephone includes a detection circuit for detecting the control signal and actuating a power rationing switch to switch the telephone to the power-up state.  The power rationing switch may also be actuated momentarily when the telephone goes from the idle to busy condition to initiate a call so as to signal the exchange of the requirement for full operating power.  The exchange is capable of deciding whether a telephone wishing to power-up can do so without causing exceeding of an allowable sum of power ration for the telephones of the system.  A test centre for digitally testing the lines between the exchange and the telephones is also disclosed.  The test centre causes a digital test signal to be transmitted from the exchange to d telephone at the end of a line under test wherein it is modified in a particular way and transmitted back to the exchange.  The returned test signal is compared. at the test centre. with a similarly modified non-transmitted test signal enabling a count of the errors to be made.  The S/N ratio on the line under test is reduced to increase the errors.

Abstract: ABSTRACT OF THE DISCLOSURE A method is provided for removal of excess water which tends to build up in recycle streams and reduces the rate of pure acid production during operation of a distillation system for purification of crude acetic acid containing waster and methyl iodide, The crude acid is introduced into the upper half of a distillation zone. The methyl iodide, a major proportion of water ant an equivalent amount of acid are removed overhead from the zone. A minor proportion of the water containing a small amount of acetic acid is removed as a liquid sidedraw at a point near the top of the distillation zone. A product acid stream essentially dry and substantially free of methyl iodide is removed from the bottom of the distillation zone. The overhead stream can be stored, disposed of or preferably recycled to the acid-producing stop, The liquid water sidedraw may either be discarded or subjected to rectifica-tion for recovery of acid values,

Abstract: ABSTRACT OF DISCLOSURE     A method of forming an injection moulded lining on a valve body comprises the step of defining a cavity having a main portion which when filled with lining material forms the desired lining, and an exten-sion portion continuous with an edge of the main portion.          Lining material is injected into the extension portion until the cavity is filled.  Any sprues produced by the injection are on the tab formed by the material in the extension portion and not on the lining proper.  Thus, there is no danger of damaging the lining as sprues are removed, and they do not cause local stress in the lining.

Abstract: ABSTRACT OF THE DISCLOSURE           A low-viscosity ink ball-point pen has a tip press-fitted at its rear end into a forward end of a barrel member housing an ink source therein.  A ball is rotatably held in a ball socket at the forward end of the tip and supplied with ink from the ink source through an ink-feeding capillary element extending from the ink source into an axial hole formed in the rear end portion of the tip and extending toward the ball socket.  The ball socket and the hole are communicated by a reduced axial passage extending between the bottoms of the ball socket and the hole.  The forward end portion of the ink-feeding capillary element cooperates with the bottom of the hole to define a substantially closed chamber of a substantial volume whereby a substantial quantity of ink can be accumulated therein for uninterrupted writing for a long period of time.  In addi-tion, the effective cross-sectional area of the capillary element through which ink can flow toward the ball, is increased with resultant increase in the rate of ink supply through the capil-lary element to the ball.
